Is 'primer' ever a verb?

If you primer your walls, then the stuff you do it with is a primerer. Or you, the person doing it, are the primerer.

Then could the wall also be called the “primee”?

Isn’t the English language fun? You can twist almost any rule, and make up new words, and still have it mostly understandable.
